ADJUSTABLE PENCIL Henman.

Application sied February i5, 1925. semi ivo. 88,178;

rlhis invention relates to a pencil holder.

pencils always desire a longpencil. Others desire a short pencil., whilesome always desire a pencil of a. particular length.

`lccordingjly it is an object of this invention to provide a pencilholder which is extensible or adjustable so that the desired Combinedlength of the pencil and holder may be obtained by the user, and that asthe pencil wears down, the holder may be lengt-hened so that the properlength is always obtainable Y The invention comprises the novelstructure ano combinations hereinafter described and more particularlypointedy out and defined in the appended claim.

ln the accompanying drawings-which illusf trate a Vpreferred embodimentof this invention and in which similarreference numerals refer tosimilar features in the differentviews Figure l is an elevational viewof the pencil holder involving,` this invention and equipped with apencil. i

Figure 2 is a part sectional and part'elevational view thereof.

Figure 3 is a view similar to Figure 2, but showing the holder adjustedin view of a shorter pencil.

Figure Il is an enlarged sectional view upon the line lV-lV of Figure l.

Figure 5 is a fragmentary sectional view ol' a slight modification.

its illustrative of this invention, there isv shot-in a p i of membersl. and 2 which are connected for longitudinal adjustment, whereby theeombined length thereofmay be varied. These members are preferably oftubular form and they may be made of any suitable material. they areshown as made of metal.

dlhile the longitudinal adjustment of these members may be effected invarious ways, I prefer a threaded connection as illustrated in thedrawings whereby relative rotation of the members will produce thedesired adjustment, the member 2 being` preferably threaded in themember l. Y

rlhe free end of the memberv 1 is designed for containinv' a pencil 3,and the free end of` the member Q, is designed for retaining an eraseril which may be Screwed into the threaded end of the member 2.

In the present instance,

i y rlhe terminal portions of the member l are lt well known that someusers of lead smooth and not threaded, only an intermediate portion ofthe member l is threaded.' These terminal portions are split asindicated at 5 and provider1 with upwardly offset cani portions (i.Metal bands 7 y'are slidably mounted upon these terminal portions andwhen these bands are adjusted over the cam portions 6, they will exert aclamping action to bind the pencil 3 in the holder, and the niembei 2 inthe member l. These bands are confined between suitably spaced stop ribs8 and 9 on the member l. `When the bands are shifted against the stopribs 9, the clamping action will be vrelieved,as is obvious.

ln Figure 5, there is shown a slight modification of the `clamping meansfor clamping the pencil in the holder and for clamping the extensionmember in adjusted position. It will be noted that the pencil holdingmember l is externally threaded throughout itsex-k tent and that theends have ClivergginfiV or sloping' surfaces, as indicated atb, to`provide la wedging` or clampingl action when the internally threadedbands *la are threaded thereon.

lt will be appreciated that this holder can ybe readily adjusted toprovide the proper lengt-h, and that it can be cheaply manufactured andassembled, and that as the pencil wears down, it can be lengthened byadjustinentto maintain a predetermined length. i

l am aware Vthat many changes may be made. and numerous details ofconstruction may be varied through a'wide range without departingi` fromthe principles of this invention, and l therefore do not purposelimiting tl e' patent granted hereon, otherwise than necessitated. bythe prior art.

l claim as this invention t ln an extensible pencil holder, a hollowmember having` a split end with a raised poih` tion, a ring surroundingsaid split end, a second hollow member in threaded relation with *l ft`b 'l 0' b 0' l`"t 1'le tie us mem ci, sain iin ein,D siii ao c over saidraised portion for clamping said members together.

In testimony whereof l have hereunto subscribed iny naine.
